This invention relates to seal presses and has for its object theprovision of an improved arrangement of parts by reason of which theseal elements can be quickly and easily removed from the press andothers substituted therefor. Improved means is provided also for lockingthe press in closed condition so as to make it compact and convenient tocarry, the arrangement preferably being such that the spring-connectedseal members when removed from operative position can be pressedtogether and fitted between the handle and the operating lever of thepress so as to be held releasably in position by the pressure of theconnecting spring.

t is a further object of this invention to improve presses of this typein sundry details hereinafter pointed out, the preferred means by whichthe several objects have been accomplished being illustrated in thedrawing, in which Fig. l is a face view of the preferred form of thepress;

' Fig. 2 isa view of the press as seen from the left in Fig. 1, but withthe operating lever in its closed position;

Fig. 3 is a top plan View of the press as seen in Fig. 2;

Fig. 4 isa vertical cross sectional View taken at the line ll--l of Fig.3; i y

Fig. 5 is a face view of a fragmentary portion of thepress correspondingto a portion of Fig. l but with the operating lever in changed position;

the line 6--5 of Fig. 4;

Fig. 'l is a perspective View of the yieldingly connected seal membersremoved from the press; and

Fig. 8 is a View similar to Fig. 4 but showing the seal members removedfrom operative position and held by friction in changed position forconvenient storage of the press.

Referring now to the several `figures of the drawing, in whichcorresponding parts are vindicated by the same reference characters, I5indi cates a frame member in the form of a channel, comprising arms I6and I'I connected by an intermediate web portion I8. As is clearly shownin Fig. l, each of the arms of the channel member I5 is provided with adeep notch I9 in one side portion so as to receive connected sealmembers 2b and 2i thereinto.

In the arrangement shown, the seal member 2l is provided with a stiffarm 22 rigidly connected therewith and extending laterally therefrom.The seal member 20,in the construction lillus- Fig. 6` is a verticalcross sectional View taken at y trated, is provided with a comparativelyvery yielding resilient arm 23 iixedly connected with the seal member atone end and likewise extending laterally therefrom. ".As is'best shownin Fig.

7, the arms 22 and 23 are strongly connected to- 5 75' together thespring arm 23 and the cooperating l0* connecting means cause the sealmembers to move into cooperative relation to each other.

As is best shown in Fig. A8, rthe seal member 2I is provided with twoopenings 24 therein which are adapted to be brought into engagement with15 lugs 25 carried by the frame arms II and Il for holding the connectedseal members releasably in fixed position in the framework, withy theseal members extending into the notches I9 of the frame arms. Connectingarms 22 and 23 can be inserted readily between the frame arms I6 and Ilfrom the left in Fig. l, the seal membersl 20 and 2l being pressedtogether to the necessary extent for enabling them to ybe inserted inthe notches Iii. opening 2li in the seal member 2l are then brought intooperative engagement with the lugs 25,

whereupon the seal members are permitted to separate slightly under theinfluence of the springA arm 23. bers are maintained inposition, withthe seal member 2| held stationary andthe seal member 2D movable towardand from the seal'member 2I, such movement of the seal member 2U beingeffected without any tendency for the connected 35 seal members to bedetached from the frame.

For effecting a movement of the movable seal member 20 toward and fromthe stationary seal member 2|, I have provided an operating lever 26formed of sheet metal bent into a channel for- 40 mation, such leverbeing pivotally mounted in position upon the arms I6 and yIl by means ofa pivot pin 2l extending across the frame member I5 transverselythereof. Upon the lever 26 in eccentric position with respect to thepivot pin 45 2l, I have mounted a segmental roller 28 by means of apivot pin 29, such roller 28 being cut away at its upper side portion soas to have clearance with respect to the pivot pin 2l of the operatinglever 26. The arrangement is such that upon a stroke of the operatinghandle 26 in clockwisedirection in Fig. 1 the roller 28 is presseddownwardly on l the seal member 2|] for moving it into cooperativerelation with the seal member 2 I, as is best shown in Fig. 4. Thedownward movement of the roller The arrangement is such that the 20'"-The 25 Under these conditions the seal mem- 30;-,

' 28 applies substantially a toggle pressure eiect upon the movable sealmember 2G for pressing it downwardly with a minimum of effort on thepart of the operator.

Means is provided in connection with the operating lever 2S for holdingthe lever in its closed position. This means comprises a plate 3D oilsetslightly at an intermediate point so as to permit the platey to beslidably mounted to advantage upon the web of the channel-formed lever26, with the plate extending through an opening 3l in said web portionas is best shown in Figs. 4 and 8. At its outer end, at the left in Fig.1, the plate 30 is provided with a downwardly turned end portion 32which is cut away partially to provide a transversely extending lug 33.This lug 33 is in such position with respect to the lever 26 that whenthe lever is in its lowered position as shown in Fig. 5 said lug 33stands directly opposite the space between a lug 34 on the handle and ashoulder 35 on the frame arm I6. With the parts in the position as shownin Fig. 5, the plate 30 may be given a slidable movement toward theright in Fig. 5 to the position as shown in Fig. 4 in which the lug 33,by engagement with the lug 34 and the shoulder 35, serves to lock thehandle 2S in its lowered position.

Upon the pivot pin 21'! (see Fig. 4), I have mounted a coiled spring 36having one end portion in engagement with the lower face of the plate3i] and its other end portion in engagement with the segmental roller23. The spring is so arranged as to press downwardly upon the roller andupwardly upon the plate, serving normally to hold the roller 28 inoperative position for engagement with the seal member 20 and to pressthe plate 36 into frictional engagement with the handle 26 for causingthe plate to remain in any adjusted position to which it may be moved.

In the arrangement shown, the frame member l5 is extended toward theright in Fig. 1 some little distance beyond the ends of the notch l5) soas to provide a handle 3l positioned directly opposite the handleportion of the operating lever 26.

It is believed to be unnecessary to describe in detail the operation ofymy improved device.

When the device is to be used, the lever 26 and the handle 31 arepressed together so as to bring the seal members 26 and 2l intocooperative relation to each other. If it is desired to use the presswith a plurality of sets of spring-connected seal members, the removalof one set of seal members and the substitution of another set can bevery quickly and easily effected. When the press and seals are to bepacked for storage or for transportation, a set of the connected sealmembers can be inserted between the arms of the channel frame member asshown in Fig. 8, the spring 23 serving to hold the seal members infrictional engagement with the frame arms I6 and Il so as to hold theseal unit releasably in position.

While I prefer to employ the form and arrangement of parts as shown inmy drawing and as above described, it is to be understood that myinvention is not restricted to the form shown except so far as the claimmay be so limited, since changes might well be made in the form andarrangement of parts without departing from the spirit of my invention.

I claim:

In a-seal press, the combination of a frame member having a deep notchopen at one side of the frame, two seal members, means movablyconnecting said seal members together and normally holding themyieldingly in slightly spaced relation to each other, means for holdingsaid connected seal members releasably in said notch of the framemember, a lever pivotally mounted on a transversely extending pivot pinbetween two transversely spaced portions of the frame, a rollerjournaled on said lever in position to apply a toggle pressure effect onone of said seal members for forcing it into operative engagement withthe other seal member upon an operag tive stroke of the lever, saidroller being mounted in slightly eccentric position with respect to thepivot pin of the lever and being cut away at one side portion so as toclear said pivot pin, a locking plate slidably mounted on said lever, ashoulder on said frame member adapted by engagement with said lockingplate to hold said lever releasably in position for maintaining saidseal members in operative engagement with each other, and a springbearing on said roller and on said locking plate serving to hold theroller normally in position for operative engagement with one of saidseal members and to press said locking plate into frictional engagementwith the lever for holding the locking plate normally in any adjustedposition to which it is moved.
